Removal device for oil stain on water

Abstract

A removal device for oil stain on water comprises a shell, a sensor, a first valve, a second valve, a third valve, a liquid inlet cup, an impeller, a piston, a first motor, a water pump and a controller. The inner cavity of the shell is divided into an oil-water separation chamber, a water storage chamber and an equipment mounting chamber. The first valve disposed at the top wall of the oil-water separation chamber is combined with the liquid inlet cup, two parallel guides are disposed on the inner wall of the oil-water separation chamber, an oil outlet and a water outlet are formed on the upper portion of the oil-water separation chamber and combined with the second valve and the third valve respectively, and the sensor is mounted below the oil outlet. The impeller is disposed in the oil-water separation chamber and placed on the piston. The first motor, the water pump and the controller are all mounted in the equipment mounting chamber. The controller is connected with the first valve, the second valve, the third valve, the sensor, the first motor and the water pump. When the removal device for oil stain on water is disposed below oil stain on water for use, air is prevented from entering the device, the oil stain is removed by gravity and pressure difference, the oil stain is centrifugally moved by rotation of the impeller so as to separate oil and water, and accordingly operating efficiency is improved.

Description

technical field [0001] The invention belongs to the field of removing oil stains on water surfaces, in particular to a device for removing oil stains on water surfaces in rivers, lakes and oceans. Background technique [0002] Leakage accidents often occur in oil tankers, oil fields, oil wells, etc. After the ship sinks, the fuel oil in the oil tank can still leak out for a long time. These accidents will cause water pollution in rivers, lakes or oceans. According to statistics, as many as 500,000 tons of oil flow into the sea due to shipwrecks all over the world every year. In response to these accidents, people usually use fences, put oil-absorbing felts and other methods to deal with the oil stains, and some areas even use tools such as small scoops and spoons to manually pick up the oil stains. This is not only too slow and inefficient, but also requires a lot of manpower and labor. financial and material resources. [0003] At present, the existing water surface oil p...

In response to these accidents, people usually use fences, put oil-absorbing felts and other methods to deal with the oil stains, and some areas even use tools such as small scoops and spoons to manually pick up the oil stains. This is not only too slow and inefficient, but also requires a lot of manpower and labor. financial and material resources

[0003] At present, the existing water surface oil pollution removal devices on the market are mainly oil cleaning ships. Although the efficiency of oil pollution removal has been improved, due to the use of suction for operation, air may be sucked in during the suction process, causing safety hazards. In addition, the oil collected by the oil cleaning ship needs to be treated by an oil-water separation device before the leaked crude oil can be recycled
